Trying to do something that should be simple. Using sed to remove the first part of a hostname but not working. I want: abc.def.com to become def.com I tried a lot of variations of the following but it's either greedy or does nothing. sed -e 's/^.*?[.]//' Thanks in advance.

Starting a URIBL - Howto? [OT]

I was just wondering from those of you who have done it - how to start a URIBL. I'm guessing the process (simplified) is: 1) Mine messages for links 2) Subtract out anything matching a fairly large white list So my first question here is - what do most of you used to mine the links in a messag

there's really nothing stopping spammers from putting in amazon.com, google.com, yahoo.com, etc. and they can be pretty sure these domains are whitelisted already by the uribl organizations. On Wed, Apr 23, 2008 at 01:51:10AM +0200, Benny Pedersen wrote: On Tue, April 22, 2008 23:47, Marc P
